Chapter 8, Problem 8.19P

(a)

Interpretation Introduction

Interpretation:

The shape and bond angle of ${\text{SeOCl}}_{\text{2}}$ ion has to be predicted.

Concept Introduction:

VSEPR theory:

The key postulate of the theory is that the shape of a molecule is determined by minimizing the mutual repulsion of the electron pairs in the valence shell of the central atom.

The steric number is a sum of the number of ligands and lone pairs surrounding the central atom.

  $\text{steric}\text{number}\text{=(m+n)}$

where m is the number of ligands and n is the number of lone pairs.

(b)
